Boat trailer

ABSTRACT

A personal water craft such as a water ski jet pulls a boat trailer that is designed to carry extra baggage for personal use or other endeavors. The boat trailer is designed with two hulls that are separated from each other to form a tunnel there between. The tunnel is designed to accommodate the high pressure water stream that is emanating from the water jet ski without upsetting the balance of the towed vessel. The boat trailer has a top container installed on the basic structure by leaving foot rests on a planar surface. The top container has a cushion thereon for a person to sit on and with the feet of that person resting on the foot rests. A handle bar provides safety for the person sitting on top of the container. The top of the container has a hinged cover thereon to be able to gain access into the interior of the top container and the interior of the basic construction of the boat trailer.

FIELD OF THE INVENTION

The invention discloses a boat trailer that is attached a ski jet or a personal water craft and is to be towed by the same. The boat trailer can be used for carrying or transporting another person and for storing items that cannot be stored on the jet ski water craft.

BACKGROUND OF THE INVENTION

The use of ski jets or personal water crafts is well known. These crafts normally carry only one person or in some cases a second person sitting behind the first person or the driver of the craft. Such crafts are quite compact and are not designed to carry many items for personal use of the driver and/or the second passenger. Towed trailers are known in conjunction with motor cycles. Motor cycles face the same problem of not being able to carry many extra items of luggage or personal use. Such motor cycle trailers are constructed as containers having a closeable top to conceal whatever is stored in the container and to water proof the content in inclement weather. Such a motor cycle trailer is not suitable to carry an extra passenger because of safety concerns. There is a tow bar between the two vessels.

The basic concept of the motor cycle trailer has to drastically changed when designing boat trailer for a personal water craft. The hull must be designed in a certain way to avoid the high powered water stream emanating from the ski jet so that the balance or attitude of the towed boat trailer is not being disturbed.

BRIEF DESCRIPTION OF THE INVENTION

The boat trailer has the shape of a normal boat with a curved bow and a straight rear end. The boat is a vessel for transport by water and on water and is so constructed to provide buoyancy by excluding water from the interior and is so shaped to provide stability while being towed. In order to enhance the stability of the boat trailer, the bottom of the boat trailer is not a single hull but is constructed to resemble that of a catamaran including two hulls that are spaced from each other to provide a tunnel so that the high powered stream of water emanating from the water exhaust of the towing water craft passes through the tunnel and underneath the trailer without disturbing the stability or balance of the towed vessel. Another advantage of the double hull construction is that boat trailer can easily by pulled out of the water and onto a beach, whereby the spaced apart hulls will stabilize the boat without tipping over as a one hull boat would do. The boat trailer is so constructed that many items can be stored therein, such as luggage or picnic essentials including food. The top of the boat trailer can be opened by way of a cover having a hinge and must be sealed against moisture or water entering into the interior of the storage area. The top of the cover can receive or can be made as a cushion for a person to sit on when traveling on water. A forward handle would be instrumental for the person to hang onto when traveling for reasons of safety.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to FIG. 1 there is shown a towing vessel 1 and a towed vessel 2. The towing vessel 1 is a well known construction of jet ski or personal water craft they may come in many different models, but the basic concept remains the same and that is to use it as a towing vessel to tow the boat trailer 2. The boat trailer is preferably made or molded of fiberglass. This is preferred to increase the durability of the vessel, the sturdiness and the water proof characteristic of the vessel at 3 there is shown a tow bar between the two vessels. It should be a rigid connection to enhance the position between the two vessels when traveling so that they cannot collide with each other. On the other hand, the tow bar 3 should be hinged at each end to the towing vehicle 1 and the towed vehicle 2. This a must, so when traveling, each of the vessels can follow its own water wave action. FIG. 1 also shows the bottom construction of the boat trailer as consisting of two hulls 4. This construction contributes to the stability of the towed vessel while at the same time allowing the water jet stream coming from the towing vessel to pass under the boat trailer without disturbing the travel of the towed vessel. This phenomenon will be further described reference to FIGS. 5 and 6. The bow of the towing vehicle is shown at 5 and the front of the towed vessel 2 should be the same to offer the least resistance to the water when traveling.

The top of the boat trailer shows a container 6 which is so constructed that the sides of the container are moved inwardly relative to the outside of the boat trailer itself. In doing so, a flat foot path or rest 12 is created. The top of the container 6 has a container cover 7 with a cushion thereon. A person may be riding on the cushion of the cover 7 and hang on to the handle bar 8 while the feet of the passenger can rest on the foot rest 12. The foot rest can also be used to stand on or walk on while taking care of the content of the container 6 which may extend all the way into the depth of the boat 2.

The tow bar 3 is connected to the towed vessel or trailer boat at 9 and to the towing vessel at 10. As mentioned above, the tow bar connections must be hinged to both vessels so that each vessel can follow the water wave actions independently of each other. The hinges on both vessels should be multi-directional so that the tow bar can move between the vessels in an up and down or sideways direction such connections could a be simple closeable hook assembly or a universal joint arrangement.

FIG. 3 is atop and rear perspective view of the boat trailer and the same reference characters are used as were explained in FIGS. 1 and 2. Both tow bar 3 connections 9 and 10 are shown in this Fig.

FIG. 4 is a perspective view of the boat trailer with its cover 7 in an open position. The cover 7 is hinged to the top container by of a hinge 11.

FIG. 5 is a rear view of the boat trailer 2 with its two hulls 4 clearly shown. The tunnel created by the two hulls 4 clearly shows the rear end of the ski jet 14 with its water jet exhaust shown at 15. The water line of the two vessels is shown at W.

FIG. 6 illustrates the towing vessel 1 and the towed vessel 2 from the bottom view. The outline of the two vessels is clearly shown with the bow 5 of the towing vessel indicating the direction of movement. Again the two separated hulls 4 of the towed boat trailer 2 clearly shows the water exhaust high pressure water stream 15W moving the tunnel created by the two hulls 4. As mentioned above, this construction greatly contributes to the stability of the towed boat trailer while moving through the water.
